Final answer:
Having special concern for the long-range consequences of present actions refers to an Ethical Principle, closely aligning with the ethical theory of consequentialism.
Step-by-step explanation:
"Having special concern for the long-range consequences of present actions" is most closely associated with an Ethical Principle. This is because it involves a consideration of the morality of an action based on its outcomes or consequences. Within the framework of normative ethical theories, looking at the long-term impacts of one's actions aligns with consequentialism, a moral theory that emphasizes the importance of the results of our actions to determine their moral value. Consequentialism asserts that an action is right when it produces the greatest overall good. In contrast, a Core Value might represent an underlying belief that influences behavior, a Rule of Conduct often refers to specific guidelines within an organization, and an Enforcement Procedure pertains to the methods of ensuring rules are followed. However, a principle that guides the moral assessment of actions based on their long-term effects squarely fits within the realm of an ethical principle.
